Environmental Protection Agency April 29, 2016 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is approving the State of Tennessee's May 23, 2014, State Implementation Plan (SIP) revision, submitted through the Tennessee Department of Environment and Conservation (TDEC) on behalf of the Shelby County Health Department (SCHD), seeking to modify the SIP by removing the Inspection and Maintenance (I/M) program in the City of Memphis, Tennessee, and by incorporating Shelby County's revised maintenance plan for the 1997 8- hour ozone national ambient air quality standards (NAAQS). Among other things, the revised maintenance plan updates the emissions inventory estimates and the motor vehicle emissions budgets (MVEBs) for the years 2006 and 2021, and contains an emissions reduction measure to offset the emissions increase expected from the termination of City of Memphis I/M program. EPA has determined that Tennessee's May 23, 2014, SIP revision is consistent with the applicable provisions of the Clean Air Act (CAA or Act).

The Environmental Protection Agency (EPA) is taking final action to approve revisions to the Arizona State Implementation Plan (SIP) under the Clean Air Act. These revisions include rescissions of outdated test methods and performance test specifications. The intended effect is to rescind unnecessary provisions from the applicable SIP.
